The Coggin Lures Copalure Invert has 12" skirt saddles with a zero-angled inverted/cupped nose with 4-hole jets. Double tapered with the "hump" pretty much in the middle of the head with a deep cup. Head is very similar to the Medium Copalure Invert except that it is about twice as long - same skirt saddle size. Awesome head for Ono/Wahoo, Ahi/Tuna, and Marlin.
This particular head has four black Mother of Pearl slabs covering the insert with a clear resin pour. These real Mother of Pearl slabs are famous with their hand-cut and individually placed design. These inserts are extremely gorgeous and are much better in person than can captured on a photo. Skirted in black/orange fleck over pink.
